I've always had 3 deep wrinkles around my neck since my teens even though I was not a big beach goer and always applied sunscreen top to bottom. I have to say that I love this treatment! It's a rich, moisturizing cream that is quickly absorbed by the skin. I apply it morning and night immediately after using Dr. D's Hydroshield Serum. After that, I apply Dr. D's Day Defense Cream with SPF 30. My neck lines are still there but they are a little less noticeable and my neck and chest area feel moist (NOT GREASY) and supple all day and night. I believe that this treatment used in combination with Dr. D's other products will prevent any new lines from appearing. Thanks, Dr. Denese!
